- Abstract
- The magnetocaloric effect (MCE) of melt-spun Fe64Mn15-xCoxSi10B11 amorphous alloys with x = 0, 0.2, 0.5, 0.7, and 1.0 was evaluated with the aim of maximizing the magnetic entropy change close to the room temperature. The peak magnetic entropy change, vertical bar Delta S-M(pk)vertical bar for Fe64Mn15Si10B11 at 309 K at H = 15 kOe was limited to 0.82 J/kg K. The magnetic properties and ensuing MCE were very sensitive to the Co content that it is conjectured that with a smaller amount of Co addition the vertical bar Delta S-M(pk)vertical bar can be optimized while maintaining the Curie temperature near room temperature. It was also shown that the Fe64Mn15-xCoxSi10B11 amorphous alloys obeyed the master curve behavior as the magnetic entropy change curve collapsed on to a single universal curve. (C) 2011 Elsevier B.
